Exhaustipated is the feeling one has when he is so tired he just doesn't give a shit. It was my mother's expression when she put in an exhausting day of work and came in so tired she didn't want to cook, turn the bed down or use the effort to shit.

I worked my fingers to the bone, my ass is dragging and I'm as exhaustipated as a push-me pull-you. A push-me pull-you is any animal with a head on both ends and no asshole so it can't shit even after a whole day of trying.
